I have HUNDREDS of MTS's in all of my tanks both sand and gravel. They do help with detritus clean up but they also contribute their own waste as well so it's like two steps forward and one step back. They don't help much with cleaning green algea in my tanks. They do however help keep the sand shifting to prevent gas pockets.
